Shaped loudspeaker output in a communications handset
First Claim
1. A mobile communications handset comprising:
- a housing having a first lateral side, a second lateral side, and a longitudinal end;
a wireless transceiver disposed within said housing for transmitting and receiving signals;
an antenna coupled to the wireless transceiver, the antenna traversing from the first lateral side to the second lateral side and spaced at least partly from the housing; and
a loudspeaker port passing through the space between the antenna and the housing.

Abstract
Loudspeaker sounds in a communications handset may be amplified in predetermined frequency ranges through positioning the loudspeaker between ported and unported spaces. In one embodiment, an empty volume of space disposed in front of the loudspeaker is included to shape the frequency response of the loudspeaker. A port connecting this volume of space to the environment may be located at a longitudinal end of the handset. In one embodiment, the port may pass through a space formed by an antenna loop. An additional empty volume of space may be disposed behind the loudspeaker to further shape the frequency response of the loudspeaker.

15. A method of shaping loudspeaker output in a communications handset, the method comprising:
-
providing a loudspeaker in a communications handset for selectively operating the communications handset in a speakerphone mode;
exciting resonant frequencies within a predetermined range by emitting sounds from the loudspeaker; and
porting the loudspeaker sounds out to the environment through an antenna loop. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of shaping loudspeaker output in a communications handset, the method comprising:
-
providing a loudspeaker in a communications handset for selectively operating the communications handset in a speakerphone mode;
positioning the loudspeaker between a front acoustic volume and a rear acoustic volume thereby increasing the frequency response of the loudspeaker in a predetermined frequency range; and
directing sounds produced by the loudspeaker out to the environment through a longitudinal end of the communications handset. - View Dependent Claims (23, 24)
